Description

Keyboard sterilizer with increased sterilization efficiency

The present invention relates to a keyboard sterilization device with improved sterilization efficiency, and more specifically, by selecting the sterilization method as a general mode or a concentrated mode according to the size (area) of the sterilization target accommodated in the storage space (S) in which the keyboard is accommodated. By being configured to be operational, it is possible not only to maximize the efficiency of sterilization and disinfection, but also to reduce unnecessary power consumption, to significantly reduce component failure and replacement, and to completely block UV leakage to the outside of the storage space to improve safety. It relates to a monitor stand for keyboard storage that can be significantly raised.

Recently, with the advancement of the electronic device industry and the expansion of communication infrastructure, the penetration rate of desktop PCs increases exponentially, and the time spent using PCs also increases significantly.

In general, a computer consists of a main body that performs a computing function, and accessories such as a monitor and keyboard connected to the main body, and the monitor and keyboard are mainly used while being seated on a desk or table.

Since these monitors and keyboards have a relatively predetermined volume and occupy a large area of the desk regardless of whether they are used or not, they reduce the desk space and reduce the usability, practicality and convenience of the desk, and the keyboard is exposed to the outside as it is. Because it is used in a pre-treated state, there is a problem of being easily contaminated and introduced by dust and foreign substances.

Accordingly, while providing a storage space for accommodating the keyboard, a monitor stand for storing the keyboard in which the monitor is seated on the upper surface has been developed and used.

Meanwhile, in recent years, interest in personal hygiene is increasing due to the improvement of the overall social income level and living standards, and accordingly, there is a method for sterilizing bacteria and viruses inhabiting various items such as smartphones, shoes, water purifiers, and toothbrushes. Various sterilizers are on the market.

In particular, since the keyboard is in direct contact with the user's finger, there is a high probability of being contaminated with germs such as viruses and bacteria.

Moreover, in the case of a PC used by a large number of people, such as a PC room, due to contact with unspecified users, the pollution state of the keyboard is further reduced, and there is no choice but to be seriously contaminated with various bacteria and pathogens.

Accordingly, various studies are being conducted on a monitor stand for keyboard storage equipped with a UV LED lamp, which is recently used as a representative sterilization method.

1 is a perspective view illustrating a hybrid stand for a monitor and a keyboard disclosed in Korean Patent Registration No. 10-0917424 (Title of the Invention: Hybrid stand for monitor and keyboard).

The hybrid pedestal for monitor and keyboard (hereinafter referred to as the prior art) 100 of FIG. 1 includes a main body 110 in which a receiving groove, which is a space in which a keyboard is accommodated, is formed inside a housing having an open lower portion, and a draw-out groove of the main body. It consists of an opening and closing door 120 formed to open and close.

In addition, the main body 110 is provided with a sterilization lamp (not shown) to sterilize the keyboard inside the receiving groove, and the sterilization lamp is in an operation standby (ON) state when the opening/closing door 120 is opened, and a reset time is set when the sterilization lamp is closed. It is turned on (OFF) for (10~30 seconds).

The prior art 100 configured in this way not only improves the appearance before and after use by installing an opening and closing door that is drawn out in a sliding manner on the front side in which the keyboard is accommodated, but also installs a separate sterilization lamp inside to protect the keyboard stored therein. It has the advantage of being able to sterilize.

However, in the prior art 100, a fixed sterilization method using a single type of sterilization lamp, that is, since the sterilization lamps are irradiated with a fixed frequency, arrangement and irradiation intensity, etc., regardless of the size (area) of the sterilization target All sterilization lamps are irradiated, which causes unnecessary power efficiency to decrease.

For example, the prior art 100 is effective when the sterilization target is a keyboard because it is manufactured by limiting the sterilization target to a keyboard and is configured to be irradiated with sterilization lamps corresponding to the size of the keyboard. Even if you want to sterilize items that are relatively smaller than the keyboard, such as a keyboard, the sterilization light source is irradiated over a wide area and unnecessary power consumption occurs.

In addition, in the prior art 100, when the opening/closing door 120 is opened, the sterilization lamp is in contact with the contact switch and the sterilization lamp is turned 'OFF'. is operated Accordingly, in the prior art 100, in order to configure the opening/closing door, it is necessary to provide components such as a guide protrusion, a door tube, and a guide groove, so that manufacturing is complicated, and parts failure and replacement occur frequently. In addition, since the contact switch turns on/off the sterilization lamp through physical contact, wear and tear of the contact part of the contact switch is high. In addition, since the opening/closing door 120 must be operated when the keyboard is stored and taken out, the convenience of use is deteriorated.

The keyboard sterilization device 1 according to the first embodiment of the present invention installs UV-C LEDs and visible light LEDs on the upper surface of the receiving groove in which the keyboard is accommodated, and at the same time UV-C LEDs according to the size (area) of the sterilization target. It is configured to operate by selecting the safe mode or concentrated mode for their irradiation method, and since the housing is manufactured as one piece through die casting, it is possible to maximize sterilization and disinfection efficiency as well as reduce unnecessary power consumption. , parts failure and replacement can be significantly reduced, and UV leakage to the outside of the storage groove is completely blocked to significantly increase safety.

In addition, the keyboard sterilizer 1 of the present invention, as shown in FIGS. 2 to 5, is seated on a desk or table and includes a main body 3 in which the keyboard is accommodated, and a cover 5 coupled to the bottom surface of the main body 3 . And, a power management module (6) that controls the power supply to each port, and a UV-C LED (81) that irradiates UV-C with the keyboard housed in the main body (3) according to the control of the controller (4) UV-C LED substrates 8 on which they are mounted, an LED substrate 7 on which LEDs 71 irradiating visible light in first and second colors according to the control of the controller 4 are mounted, and a body 3 ) installed on the inner wall corresponding to the entrance forming the storage space (S), and after emitting an optical signal, the optical sensor 11 receives the reflected signal to detect an object into the storage space (S), and the body; (3) and a gyro sensor (12) installed in the installation space between the cover (5) and measuring the inclination of the keyboard sterilizer (1), and disposed directly below the storage space (S) to absorb UV-C ultraviolet rays It consists of an absorbent pad (15) and a controller (4) for managing and controlling the operation of the keyboard sterilizer (1).

6 is a perspective view illustrating the main body of FIG. 2 ;

As shown in FIG. 6 , the main body 3 is formed as a housing having a storage space S therein with front and rear openings. At this time, the keyboard 21 is accommodated in the storage space S of the main body 3 , and the PC monitor 22 is seated on the upper surface 31 of the main body 3 .

In addition, the main body 3 is manufactured in one piece through a die casting process, so it has excellent durability and strength, as well as a simple manufacturing process. In order to increase it, the problems of space consumption and material cost increase due to the installation of reinforcing structures were remarkably improved.

Conventionally, as the body is manufactured through the assembly of parts manufactured using extrusion, press, etc., durability and strength are lowered, and a separate strength reinforcement structure is installed to compensate for this. Due to this, there was a problem that the material cost increased, but as the main body 3 of the present invention was manufactured as an integral part through die casting, it did not need to install a separate reinforcing structure, and at the same time realized the desired durability and strength and compared with the prior art. It has the advantage of lowering the manufacturing cost by reducing the material cost.

In addition, the main body 3 of the present invention is made of an aluminum material with relatively excellent thermal conductivity and at the same time has a large area top plate, so that even if the volume of the heat sink size is miniaturized, heat generated from accessories such as a PD module can be effectively radiated. .

That is, the main body 3 of the present invention can solve the problem of frequent equipment replacement due to component failure and wear because the body 3 of the present invention is made of aluminum raw material in one piece through die casting. Not only that, but also has the advantage of significantly increasing durability and strength.

In addition, the lower surface 33 forming the receiving space (S) of the main body (3) is protruded in a cylindrical shape, the fastening protrusions 331 having a bolt groove on the inside are formed at intervals. At this time, the fastening protrusions 331 are bolted to the fastening parts of the cover 5 so that the main body 3 and the cover 5 are coupled. At this time, an installation space in which the

accessories

6 , 7 , 8 , and 12 are installed is formed between the body 3 and the cover 5 .

7 is a perspective view of the cover of FIG. 2 viewed from the bottom, and FIG. 8 is a bottom view of FIG. 7 .

As shown in FIGS. 7 and 8 , the cover 5 is formed of a plate with an open top, and is bolted to the bottom surface of the body 3 and coupled thereto. At this time, an installation space is formed between the bottom surface of the cover 5 and the main body 3 , and the

accessories

6 , 7 , 8 , and 12 are installed as the installation space.

In addition, a power button 511 is installed on the front side 51 of the cover 5 . At this time, the controller 4 to be described later determines the sterilization method to be 'normal mode' when the power button 511 is briefly pressed for less than the critical time by the user, but the power button 511 is longer than the critical time by the user When pressurized, the sterilization method is determined as 'intensive mode'.

At this time, the 'normal mode' means a sterilization mode in which all UV-C LEDs 81 are emitted so that the irradiation area of UV-C forms the area of the storage space S, and the 'focused mode' is the UV-C It means a sterilization mode in which only some of the UV-C LEDs 81 are emitted so that the irradiation area of the UV-C LEDs 81 is limited only to a preset quick-zone among the storage space S.

In other words, the 'normal mode' of the present invention can be applied when the sterilization target is a product having a large area such as a keyboard, and the 'focused mode' is when the sterilization target is a product having a small area such as a smartphone or a cup. , can be applied, and thus the optimal sterilization mode can be selected and used in response to the size (area) of the sterilization target, thereby increasing sterilization efficiency and convenience of use, as well as preventing unnecessary power consumption.

In addition, USB ports 513 of various standards, a USB power delivery (PD) port 514, and a power adapter port 516 are installed on the front surface 51 of the cover 5 .

In addition, first installation holes 531 in which UV-C LEDs 81 are respectively installed are formed at intervals in the longitudinal direction at a midpoint in the width direction of the bottom surface 53 of the cover 5 . At this time, in the present invention, for convenience of explanation, the first installation holes 531 are formed one by one in the width-direction, but three are formed in the length-direction as an example, but the positions of the first installation holes 531 and the quantity is not limited thereto.

In addition, a pair of second installation holes 532 spaced apart in the width direction are installed on the bottom surface 53 of the cover 5 at intervals in the longitudinal direction. At this time, the LED modules 71 are installed as the second installation holes 532, respectively.

That is, in the bottom surface 53 of the cover 5 of the present invention, second installation holes 532 are formed at each corner of the rectangle centered on the first installation hole 531 .

Returning to FIG. 3 again, looking at the LED board 7 , the LED board 7 is a board on which a circuit is printed and the LED modules 71 are mounted on the bottom surface, and the installation space between the body 3 and the cover 5 . is installed on

At this time, as described above, the LED modules 71 are respectively inserted into the second installation holes 532 of the bottom surface 53 of the cover 5 to emit light into the lower storage space S of the cover 5 . .

The UV-C LED substrates 8 are substrates on which the circuit is printed and the UV-C LED module 81 is mounted on the bottom, and installed in the installation space between the main body 3 and the cover 5 .

At this time, when the UV-C LED modules 81 are installed, the irradiation angle and direction are set so that the irradiated UV-C ultraviolet rays pass through the storage space S and are not exposed to the outside.

In addition, as described above, the UV-C LED modules 81 are respectively inserted into the first installation holes 831 of the bottom surface 53 of the cover 5 to enter the lower storage space S of the cover 5. -C Irradiate the light signal.

At this time, UV-C ultraviolet is a short wave having a wavelength of about 100 to 280 nm, and is known to have the best sterilization power.

The gyro sensor 12 is installed in the installation space between the main body 3 and the cover 5, detects the angular velocity (inclination) of the keyboard sterilizer 1, and outputs the detected inclination value to the controller 4 . At this time, when the inclination value input from the gyro sensor 12 is '0', the controller 4 proceeds with the sterilization mode as it is, but stops the ongoing sterilization mode when the input gradient value is not '0' By doing so, external exposure of UV-C ultraviolet rays was thoroughly blocked. For example, in the present invention, when a user lifts or moves the keyboard sterilizer 1 and looks at it while UV-C ultraviolet rays are being irradiated, the controller 4 measures the measured value by the gyro sensor 12. By stopping the sterilization mode through the slope value, it was possible to thoroughly prevent exposure to UV-C ultraviolet rays to the user.

The photosensor 11 detects the entry and withdrawal of an object into the accommodation space S of the main body 3 , and outputs the detected detection signal to the controller 4 . At this time, when a detection signal is input from the optical sensor 11, the controller 4 stops the ongoing sterilization mode, so that the user inserts his or her hand into the storage space S during the sterilization mode so that the user's hand comes into contact with UV-C ultraviolet rays. accidents can be prevented.

Figure 9 is a bottom view showing the UV-C LED modules and the LED modules are installed cover for explaining the quick zone of the present invention.

As shown in FIG. 9, in the keyboard sterilization device 1 of the present invention, the sterilization mode is operated in one of the 'normal mode' and the 'concentrated mode' according to the pressing time of the power button 511 by the user. The sterilization mode is determined as a 'normal mode' that emits UV-C ultraviolet rays to the total area (A) of the storage space (S) when the power button (511) is briefly pressed for less than a preset critical time, The sterilization mode is determined as a 'concentrated mode' that emits UV-C ultraviolet rays only to the quick zone A1 of the storage space S when the button 511 is pressed for a long time longer than a preset critical time.

At this time, the 'normal mode' can be applied when the sterilization target is a product having a large area such as the keyboard 21, and the 'intensive mode' can be applied when the sterilization target is a product having a small area such as a smartphone or a cup. , thus, it is possible to select and use the optimal sterilization mode in response to the size (area) of the sterilization target, thereby increasing sterilization efficiency and convenience, as well as preventing unnecessary power consumption.

Accordingly, the controller 4 of the keyboard sterilization device 1 of the present invention has only UVC ultraviolet rays from the UV-C LEDs 811 disposed in the middle among the UV-C LEDs 81 when the sterilization mode is 'focused mode'. While controlling to be irradiated, it is controlled so that only the corresponding UV-C LED 811 and the adjacent LED modules 711 emit an optical signal. At this time, the LED modules 711 corresponding to the quick zone emit light in a preset first color so that the user recognizes that the sterilization mode is being operated in the intensive mode through the color of the light source.

In addition, when the sterilization mode is 'normal mode', the controller 4 of the keyboard sterilizer 1 controls all UV-C LEDs 81 to emit UV-C UV rays and at the same time all LED modules 71 ) to control the light signal to be emitted. At this time, the LED modules 71 except for the LED modules 711 corresponding to the quick zone A1 among the LED modules 71 emit light in a preset second color so that the user can focus the sterilization mode through the color of the light source. Make sure you are aware that it is operating in mode.

In other words, the keyboard sterilization device 1 of the present invention is configured so that the user can select and operate the sterilization mode in response to the size (area) of the sterilization target, thereby maximizing the sterilization and disinfection efficiency and reducing unnecessary power consumption. It can reduce the cost and increase safety by maximally preventing unnecessary exposure to UV-C ultraviolet rays.

10 is an exemplary diagram illustrating a USB PD protocol.

The USB PD protocol will be described with reference to FIG. 10 .

In general, as a power supply technology using a data line, there is a Universal Serial Bus (USB) technology.

These USB interfaces have evolved over time in terms of data transfer rates and power supply capabilities. USB interface standard USB 1.0 can support data transfer speed of up to 12Mbp and power supply of 5V, and later announced standard USB 2.0 and standard USB 3.0 to support data transfer rates of 480Mbps and 5Gbps, respectively.

In particular, in the case of standard USB 3.0, it has the ability to supply power up to 900mA. However, even if power can be supplied up to 900mA according to the standard USB 3.0, the maximum power supply is only 4.5W, so it is still difficult to supply power according to the USB method for devices with relatively high power consumption such as monitors, and USB Depending on the method, it takes a long time to charge the large-capacity battery of the latest tablet or smartphone.

Accordingly, the USB Implementers Forum (USB-IF) has confirmed the USB Power Delivery (USB PD) standard, a new standard that can supply up to 100W of power using a USB cable.
